Description

Technical Field

[0001] The invention belongs to the field of pig feed, and particularly relates to a traditional Chinese medicine feed additive for pigs and a preparation method thereof. Background Art

[0002] Traditional Chinese medicine is both a treatment and a preventive and growth-promoting medicine. Traditional Chinese medicine is pure natural and has a wide range of sources. It has the functions of improving the body's immunity, preventing diseases, increasing weight, promoting growth, and health care. It contains a variety of effective ingredients and has all the functions of feed additives. It can be added to animal feed as an independent type of feed additive as a necessary additive for growth. The use of traditional Chinese medicine as a feed additive in my country has a long history. It has been used to promote animal growth, weight gain and prevent diseases as early as more than 2,000 years ago. The Huainanzi. Wanbi Book written by Liu An in the Western Han Dynasty contains the saying that hemp salt fat pigs, "Take three liters of hemp seeds, pound more than a thousand pestles, cook into a soup, add one liter of salt, and mix with three hu of bran, feed the pig, and it will be fat." The Eastern Han Dynasty human and animal general Chinese medicine monograph "Shennong Bencao Jing" contains "Feeding pigs with tung leaves, fat three times, and easy to raise." The Ming Dynasty Li Shizhen's "Compendium of Materia Medica" records that "Wu Yao, pigs and dogs have hundreds of diseases, and can be ground and taken", etc., all of which show that traditional Chinese medicine additives have a long history and reliable effects.

[0003] Modern research has found that the role of Chinese herbal additives is mainly manifested in: improving feed quality, enhancing disease prevention, health care, improving animal production performance, improving animal product quality, etc. However, the current public Chinese herbal feed additives for pigs have different opinions, the content is vague, lack of persuasiveness, and its effect needs to be further improved. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a method for preparing a Chinese medicinal feed additive for pigs. The present invention aims to solve the problem that the existing Chinese medicinal feed additive for pigs has poor effect and lacks persuasiveness.

[0005] To achieve the above purpose, the present invention provides a Chinese medicinal feed additive for pigs, which is prepared from the following Chinese medicinal raw materials in parts by weight: 500-700 parts of alfalfa powder, 120-220 parts of epimedium, 120-240 parts of angelica, 120-220 parts of immature bitter orange, 120-220 parts of astragalus, 100-200 parts of codonopsis, 100-200 parts of chickweed, 100-200 parts of atractylodes, 120-220 parts of white mulberry bark, 120-220 parts of bupleurum, 140-230 parts of rehmannia, 120-220 parts of schizonepeta, 120-220 parts of seaweed, and 100-200 parts of hawthorn.

[0006] The present invention provides a method for preparing a Chinese medicinal feed additive for pigs, comprising the following steps:

[0007] S1. Selection of Chinese herbal medicines: Prepare Chinese herbal raw materials according to the components of Chinese herbal feed additives for pigs, and select out impurities, defective and unqualified medicines;

[0008] S2. Chinese herbal medicine crushing: weigh the selected Chinese herbal raw materials according to the weight ratio of Chinese herbal feed additives for pigs, mix them evenly, and then crush them into 80 mesh fine powder. After drying, stir them evenly to obtain Chinese herbal feed additives for pigs. Drug crushing needs to consider the preparation characteristics, pay attention to the crushing particle size, disposal rate, temperature, method, etc., to ensure that it is used in the subsequent process requirements.

[0009] The role of Chinese herbal feed additives

[0010] It has the functions of preventing and caring for the health, enhancing immunity, inhibiting bacteria and expelling parasites, and promoting growth; improving animal production performance is mainly reflected in promoting growth, fattening and weight gain, and promoting reproduction; improving the quality of animal products is mainly reflected in improving meat quality, reducing allergens, and improving fur; improving feed quality is mainly reflected in the fact that many Chinese herbal additives have the functions of supplementing nutrition, enhancing fragrance and deodorizing, and preventing mildew and corrosion, thereby improving feed nutrition, stimulating animal appetite, and extending the shelf life of feed.

[0011] Characteristics of Chinese herbal feed additives

[0012] (1) Wide sources: Chinese medicine comes from animals, plants, minerals and their products. It is itself a component of nature and biological organisms, maintaining the natural state and biological activity of various components and structures. At the same time, it has been proven to be beneficial to humans and animals through long-term practical tests. Before application, it is scientifically processed and processed to remove harmful parts and maintain its pure natural properties. This feature also lays the foundation for the wide sources, economical and simple, safe and reliable nature of Chinese medicine feed additives.

[0013] (2) Diversified functions: Chinese herbal medicine has both nutritional and medicinal effects. Modern research shows that Chinese herbal medicine contains a variety of ingredients, including polysaccharides, alkaloids, glycosides, etc., ranging from a few to dozens, and as many as hundreds. According to the modern "structure-activity relationship" theory, its versatility is obvious. In addition to containing the nutrients required by the body, when used as a feed additive, Chinese herbal medicine is rationally combined according to the theory of traditional Chinese medicine to make the substances work synergistically, and produce a full range of coordinated effects and overall coordination of factors that are beneficial to the body, thereby achieving the goal of improving animal production capacity. This is also an advantage that chemical synthetic substances cannot match.

[0014] (3) Safety and reliability: For a long time, the toxic side effects and drug resistance of chemical drugs, antibiotics and hormones have puzzled the medical community, especially the easy occurrence of drug residues in animal products, which has become a problem of concern to the whole society. Traditional Chinese medicine has few toxic side effects, no drug resistance, and will not produce harmful residues in livestock products such as meat, eggs and milk. This is a unique advantage of traditional Chinese medicine additives. This advantage conforms to the trend of the times and meets people's desire to return to nature and pursue environmentally friendly, green and pollution-free food.

[0015] (4) Economic and environmental protection: The production process of antibiotics and chemical synthetic drug additives is complex, the production cost is high, and it causes "three wastes" pollution. Chinese medicine comes from nature. Except for a few artificially planted ones, most of them are wild, with a wide source and low cost. The preparation process of Chinese medicine feed additives is relatively simple, and the production will not pollute the environment. Moreover, the product itself is a natural organic matter with various chemical structures and biological activities that are stable, easy to store and transport, and not easy to deteriorate.

[0016] The present invention also provides a method for using a Chinese medicinal feed additive for pigs, comprising the following steps:

[0017] S1. Basic diet grinding: weigh each type of feed in the basic diet in proportion, stir, grind and set aside;

[0018] The formula of the basic diet: corn, soybean meal, rice bran, wheat bran, and vegetable oil;

[0019] S2. Mixing: Weigh the Chinese medicinal feed additive for pigs and the crushed basic diet according to the proportion, and then put them into a blender together to prepare the Chinese medicinal feed, package it, and set it aside;

[0020] S3 feeding: according to the feed dose required per pig per day weigh the Chinese medicine feed prepared in step S2, and then weigh the Chinese medicine feed poured into the cooking pot, add drinking water, boil for 20-30 minutes, and feed after cooling;

[0021] Feed twice a day, the first feeding at 8:30 am and the second feeding at 17:30 pm.

[0022] Beneficial effects:

[0023] 1. The Chinese medicinal pig feed of the present invention has no incompatibility taboos and can synergize. The combination of various medicines has the effects of antibacterial, anti-tumor, anti-pathogenic microorganisms, and improving immune function. It can effectively prevent or treat common diseases of pigs; enhance appetite, promote growth, shorten fattening time, and have obvious weight gain effects.

[0024] 2. The products of the pigs fed with the Chinese medicinal pig feed of the present invention are characterized by being pollution-free, pollution-free and residue-free, and have good meat quality, high nutritional value and unique flavor, and are pure natural green food.

[0025] 3.

[0063] 4. Test results

[0064] 4.1 Functions of Chinese medicine: Chinese herbal medicine is green and natural, and contains rich nutrients such as protein, minerals, sugar, etc., which can promote the growth and development of pigs. Some Chinese medicines can also regulate nutritional balance and have the effect of strengthening the spleen and stomach; some taste good and can improve the palatability of feed, making pigs more willing to eat; some can regulate the physical constitution of pigs and enhance their disease resistance. The application of each Chinese medicine in pig farming is not just one or two effects, and of course it will not be effective in one or two times. Raising pigs with Chinese herbal medicine is a long-term process. The ingredients of Chinese medicine are complex, and each Chinese medicine often contains multiple ingredients, which can produce multi-target synergistic effects in the animal body, and thus can produce different or opposite effects in the body. The present invention uses the method of frying Chinese medicine while cooking food, and adopts the method of cooked feeding, so that the food and Chinese medicine can give full play to their functions. After long-term feeding, the pigs have red and shiny skin and hair, and gain weight quickly; the reproduction capacity of the probiotic flora in the pig intestine is enhanced, the intestinal flora is improved, the bacteria, viruses, toxins, etc. in the pig body are removed, the growth and development of the pigs are promoted, and the pigs are not easy to get sick; the pigs eat the Chinese medicine and feed and cook them into cooked food, the quality of the pork is improved, not only the original natural flavor characteristics are maintained, but also the physical fitness of the human body is improved. High temperature cooking can kill bacteria in the feed, the test group has less disease and no death; the control group has more disease and death, which fully shows that Chinese medicine has the function of preventing diseases.

[0065] 4.2 Effects of weight gain and growth promotion: In order to prevent and cure diseases and promote the growth and development of pigs, more and more people have given up the use of Chinese medicine in pig farming. Because antibiotics are cheap and effective quickly, while Chinese medicine is complicated to use and the effect cannot be seen in the short term. Chinese medicine is green and natural, and it contains rich nutrients, such as protein, minerals, sugars, etc., which promote the growth and development of pigs; some Chinese herbal medicines can also regulate nutritional balance and have the effects of strengthening the spleen and stomach; some taste good and can improve the palatability of feed, making pigs more willing to eat; some can regulate the pig body and enhance the resistance of pigs. The application of each Chinese herbal medicine in pig farming is not just one or two effects, and of course it will not be effective in one or two times. Raising pigs with Chinese herbal medicine is a long-term process. Under the same conditions, the experimental group gained weight faster than the control group, gaining 26 kilograms more and gaining an additional benefit of 254.80 yuan.

[0066] Table 2: Average weight gain statistics of experimental pigs

[0067]

[0068] 4.3 Disease prevention: This product can enhance the body's immune function and strengthen the body's resistance. It can prevent the occurrence of bacterial, viral diseases and stress syndrome. Experiments have shown that the incidence of diseases in livestock and poultry using this product is reduced. From Table 3, it can be seen that the test group only had colds and diarrhea during the fattening period, and no one died. The cost of medicine was 136.00 yuan. The control group had more diseases, 15 deaths, and direct economic losses of up to 42042.00 yuan, and the total cost of medicine was 43725.00 yuan.

[0069] Table 3: Statistical table of disease incidence in experimental pigs

[0070]

[0071] 4.4 Economic Benefits: After the formula is cooked and fed, the pigs feel more hungry and eat more; they are greedy and sleepy; their skin becomes red and shiny in 5-7 days; their skin becomes pink in 10-15 days, and their body shape begins to improve. The diarrhea pigs no longer have diarrhea. Epimedium, angelica, cassava flour, and codonopsis in this formula stimulate the animal body to secrete insulin and growth hormone. It cleans the gastrointestinal mucosa, thins the gastrointestinal wall, and improves the digestion and absorption rate of feed; at the same time, this product can promote the decomposition of carbohydrates in the feed and the synthesis of non-protein nitrogen into high-quality protein. It maintains the balance of gastrointestinal flora, reduces the incidence and mortality of pigs, and increases economic benefits. As can be seen from Table 3, the economic benefits of Chinese medicine feed are considerable. The experimental group gained 26 catties more, and the experimental group spent 254.80 yuan more per head than the control group; the average weight of each head is 312 catties, 9.80 yuan per catty, a total of 3057.60 yuan; the drug cost of the experimental group is 136.00 yuan. There were 15 deaths in the control group, each weighing 286 kilograms. According to the market price of 9.80 yuan per live pig, the total cost was 2,802.80 yuan per pig. The 15 deaths cost a total of 42,042.00 yuan, and the medicine cost was 1,683.00 yuan, totaling 43,725.00 yuan.

[0072] 4.5 Pork testing: Pork, also known as pig meat, is one of the main livestock foods. Pigs belong to the Suidae family. They are sweet, salty and flat in nature. They are rich in protein, fat, carbohydrates, calcium, phosphorus, iron and other ingredients. Pork is the main side dish in daily life. It has the functions of nourishing the body, nourishing yin and moistening dryness, and nourishing the muscles and skin. Pork can be used as a nutritional tonic for those who are weak after illness, anemic after childbirth, and have yellow faces and thin skin. Pigs were slaughtered at the same time, and the same parts were taken and sent to the same unit for testing. The protein and fat content of the test is shown in Table 4. It can be seen from the table that the protein content is 7.48 higher than that of the control group, indicating that the nutritional value of the experimental group is high, and the diet and Chinese medicine play a role, proving that the effect of cooked feeding is good.

[0073] Pork Nutritional Components Test Table 4

[0074]

[0075] 4.6 Identification of pork quality: Pigs belong to the Suidae family. They are sweet and salty in nature, and have the effects of nourishing yin, moistening dryness, and nourishing muscles and skin. According to the Yellow Emperor's Classic of Internal Medicine and modern molecular theory, their cells are closer to humans, so they are more beneficial to the human body. Those who are weak after illness, anemic after childbirth, and have yellow faces and thin skin can use pork as a nutritional tonic. It contains rich protein, fat, carbohydrates, calcium, phosphorus, iron and other ingredients. Pork is the main side dish in daily life, which has the effect of nourishing the body. Pork quality identification is used to measure the factors affecting pork quality, as well as to evaluate pork quality and performance. Marbling is a texture formed by the fat connective tissue between small muscle bundles, and is an important indicator of pork quality. From the experiment, it can be seen that cooked feeding has higher nutritional value than raw feeding, tastes better, and has marble.
